Toughness and stiffness of fibre reinforced concrete in terms of shear capacity

Shear failure is generally considered to be among the most critical topics in reinforced concrete structures due to specific features such as little warning and brittle nature. Due to the complexity and high expensive costs, different models and design methods have been developed and proposed to investigate shear. Push-off is one of the most models that is used for that goal. In the current study, a total of 75 push-off specimens have been tested to investigate shear capacity of fibre reinforced concrete. There is a lack of knowledge regarding shear capacity in fibre reinforced concrete exposed to elevated temperatures. Therefore, the results of these test series including strength, toughness, and stiffness are of great importance and considered as new scientific results.
